StarPlane::Overview

• StarPlane is a NWO funded project carried out by UvA and VU with major contributions from SURFnet and NORTEL.

• StarPlane will use the physical infrastructure provided by SURFnet6 and the distributed supercomputer DAS-3.

• The vision is to allow part of the photonic network infrastructure of SURFnet6 to be manipulated by Grid applications to optimize the performance of specific e-Science applications.

• The novelty is to give flexibility directly to the applications by allowing them to choose the logical topology in real time, ultimately with subsecond lambda switching time.

StarPlane::Goals

• fast, application-specific allocation of the network resources with deterministic characteristics;

• application-specific composition of the protocol stack that is used to control the resources;

• low-level resource partitioning (and, hence, no interference);

• high-level requests (whereby policies and inference are used to assist the user).

Background::SURFnet6

In The Netherlands, SURFnet connects

between 180:- universities;- academic hospitals; - most polytechnics; - research centers.

with a user base of ~750K users

It is a part of the world wide Internet.

It is a hybrid network which offers not only regular Internet services but alsolighpaths with speeds up to 10Gbps

SURFnet6 was officially launched on 23-01-2006

Background::CPL

Common Photonic Layer (CPL)is photonic portion for lightpaths:- 6000km dark fiber network

with Nortel DWDM and TDM equipments

- 5 rings- initially 36 lambdas (4x9)- later 72 lambdas (8x9)

Each lambda with up to 10Gbps possible throughput

WSS

• WSS will allow us to redirect a selected input color to the output fiber

• This allows us to flexibly reconfigure the network according to the application demands.

• The key issue of StarPlane is subsecond switching, and topology reconfiguration.

06-06-06@UvA 12

How to make it work

• develop the interfaces between the application and the management plane;

• describe all resources in a ‘common language’; • investigate the capabilities of the various network

devices related to StarPlane;• manipulate the network devices in control plane on

demand of application;• integrate all possible solutions from different parties.

06-06-06@UvA 13

Current Progress

• App use cases: Large ‘stand-alone’ file transfers Large file (speedier) Stage-in/Stage-out App with static bandwidth requirements App with dynamic bandwidth requirements

• WS prototype development• Determine APIs for app (see next)• Investigate HW

06-06-06@UvA 14

APIs

• Examples: query_availability(site_A_to_B, bw, s_time,

diff_slot); reservation(site_A_to_B, bw, s_time,

duration); free(res_id);

06-06-06@UvA 15

Future Plan

• Finish the WS development• Research on the GMPLS simulation box in

Canada via remote access• Integrate AAA, DRAC...
